Which state has most of its area in the Central Time Zone?

• A. Minnesota
• B. North Dakota
• C. Iowa
• D. Illinois

Answer: (B)

The key idea is how time zones line up across large states and how some states sit in more than one zone. The Central Time Zone covers a big stretch of the central U.S., but a few western areas dip into Mountain Time. North Dakota is mainly Central Time, with a western strip that uses Mountain Time. That split shows up clearly on time-zone maps: most of the land is in Central, while a smaller western portion isn’t. In contrast, states like Minnesota, Iowa, and Illinois lie entirely within Central Time, so their whole land area is in that zone. The question points to North Dakota because it typifies a state where Central Time dominates the bulk of the area, even though there is a notable Mountain Time portion in the west.
